22 LM2 - P2ADA Code - Warranty (Yea or Nay?)

[parthery]

'22 LM2 has thrown the P2ADA code and reduced performance message.  It's at the dealer now....claims it needs a new DEF Controller.  Also they say it's not cover by the 100K powertrain warranty.  Truck has 88K on it.  

 

Anyone had any luck getting this covered outside of 36/36?  Apparently it's a $1200 repair.  At least the part isn't back ordered......

Have a look at the 'emissions' warranty in the warranty booklet.

 

How many miles on the 2022?

He stated 88,000 in his post.

UPDATE - The tank, harness and module all had to be replaced.   Interestingly, the tank and harness are covered by the 100K powertrain warranty but the module isn't.  I've opened a case with GM...truck runs good now...$905 later.
